Abstract

A fibre optic sensor is embedded in an integral housing block formed by moulding or extrusion. The housing block has a mounting surface for attachment to a wind turbine component by adhesive or mechanical connection. In an arrangement where the sensor is to be isolated from strains on the component, the housing block may be mounted on the component by means of a smaller mounting portion, joining the mounting portion at a neck region.
